The State of New York has reportedly filed a lawsuit against Polymarket, a platform known for hosting prediction markets. The legal action characterises Polymarket's operations as an "illegal gambling operation", according to reports.

Prediction markets allow users to speculate on future events by buying and selling shares that represent specific outcomes. The price of these shares can fluctuate based on supply and demand, often reflecting the market's collective probability assessment of an event occurring. Participants typically receive a payout if their predicted outcome materialises.

This legal challenge from New York highlights ongoing regulatory scrutiny faced by platforms operating in the decentralised finance and prediction market space. The classification of prediction markets as gambling has been a recurring debate, with implications for their legality and oversight in various jurisdictions.
